I am hesitant to call the call to this function a "check".  If you
do not yet have the leading directories, they get created.

    We make sure that the parent directory of path exists (or create it
    otherwise) and then do the same for path + "/.git".

    That is equivalent to just making sure that the parent directory of
    path + "/.git" exists (or create it otherwise).

Perhaps?
